CM Magazine: The Little Math Puzzle Contest

The Little Math Puzzle Contest

Tom Murray, the coordinator of the the math puzzle, has been kind enough to give CM permission to run the weekly Little Math Puzzle Contest (inspired by The Great Canadian Trivia Challenge.)

Royal West Academy (a high school) in Montreal, Quebec is sponsoring a little math puzzle contest.

This contest is open to all participants but is designed for students in grades five through ten. English will be the language used for all problems and if their solutions relate to a language, the language will be English.

This will be the last question before Christmas we will start up again when school begins in January. Have an enjoyable holiday.

You can find archives of old questions and winners lists on our web page. We have lost the winners list for the second puzzle and would be pleased to have it forwarded to us from anyone who still has it.

We can also be found on the Web at:

Contest Format:

Each week a new puzzle will be presented and the answers and winners from two weeks earlier will be posted. Answers are to be received by 8:00 a.m. eastern time the following Friday.

The answers will then be judged, and a correct answer, along with the winners' names, will be posted with the puzzle two weeks later.

Both individual students and entire classes are welcome to participate.

Do not to send your answers to CM.
Instead, please send all answers to Andrea Pollock and Alex Nazarov at the following address:

With your solution please include your names, school, grade, and e-mail address, and your city.
